Abstract: A station that generates data packets to be transmitted by the station such that the data packets spend a minimum amount of time in a buffer prior to transmission. The method includes receiving a specification for a connected discontinuous reception (C-DRX) cycle, the specification indicating when a plurality of onDurations of the C-DRX cycle occurs, the onDurations having a predetermined interval therebetween, receiving data at a known time relative to the C-DRX cycle, determining a modification to a conversion process that converts the data to data packets such that the data packets are stored in a buffer at a subframe immediately preceding one of the onDurations subsequent to the known time, performing the conversion process based upon the modification and storing the data packets at the subframe immediately preceding the one of the onDurations. In one embodiment, the data is raw audio data and the data packets are audio packets.

Abstract: Methods and apparatus for parameter (e.g., timing) adjustment in a wireless network. In one embodiment, the timing adjustment includes detection and compensation for one or more missed adjustment messages. In one variant, for certain designated events, a client device may ignore a timer expiration, and apply a previously stored timing advance (TA) command. For example, a user equipment (UE) will determine if a TA command has been missed during a measurement gap interval (such as e.g., to perform measurements on an unsynchronized network), and reuse the previous TA command value. Reusing the TA command value introduces negligible error, which can be corrected in existing error correction capabilities (e.g., OFDM cyclic prefixes, etc.).

Abstract: Methods and apparatus for power optimization in e.g., a wireless mobile device. In one embodiment, the optimization is effected via intelligent idle mode current drain management. In an exemplary LTE cellular network context, the user equipment (UE) only powers on its transceiver for a subset of Discontinuous Reception (DRX) cycles based on e.g., the quality of the radio environment, power considerations, location, etc. For example, if a UE has not moved, and its radio reception quality is good, the UE is likely to successfully receive a paging notification (i.e., without multiple attempts). Consequently, the UE configures itself to receive only a single paging indication.

Abstract: A method and apparatus to improve the robustness of a wireless communication link between a base station and a mobile communication device. The method increases power selectively on portions of an uplink communication signal transmitted from the mobile communication device to the base station. The method monitors a quality metric value at the mobile communication device and sets the transmit power level of the first portion of an uplink communication signal to the first power level, if the monitored quality metric value is in a first range of quality values, or sets the transmit power level of the first portion of the uplink communication signal to a second power level, if the monitored quality metric value is in a second range of quality values. The first portion of the uplink communication signal includes control signals used by a base station to maintain connection of the wireless communication link.

Abstract: Methods and apparatus enabling a mobile device to receive paging notifications from multiple networks. In one embodiment of the present invention, a first device connected to a first network momentarily ignores the first network, to monitor a second network instead. The first device identifies and prioritizes a list of applications of the first network; the prioritized listing allows the first device to preempt one of its lower priority tasks to monitor the second network for paging messages instead. The described methods and apparatus enable e.g., GSM paging for Class B cellular devices which are connected to GPRS NMO-2 type networks. The Class B cellular device can ignore certain GPRS data (which is tolerant to error), to decode GSM paging channels, which would otherwise be missed.

Abstract: A method to read selectively system information messages in a mobile wireless communication device. The mobile wireless device receives a first transmission of a multiple segment message through a radio frequency receiver. The mobile wireless device detects decoding errors in at least one of the received segments of the first transmission. In response to detecting decoding errors, the mobile wireless device selectively receives a first subset of segments in a second transmission of the multiple segment message. The mobile wireless device powers down at least a portion of the radio frequency receiver during receive time intervals for a second subset of segments in the second transmission. The first subset of segments in the second transmission corresponds to segments in the first transmission received with decoding errors. The second subset of segments in the second transmission corresponds to segments in the first transmission received without decoding errors.

Abstract: Generating a radio frequency test signal for a mobile wireless communication device from a set of scanned radio frequency data that represents a plurality of radio frequency channels over a sequence of time intervals. A segment of the set of scanned radio frequency data over a time interval is classified into one of several radio frequency environments. A subset of the segment of scanned radio frequency data is selected based on the classified radio frequency environment. A segment of the radio frequency test signal is generated using the selected subset of scanned radio frequency data. The steps of classifying, selecting and generating are repeated for each time interval in the sequence of time intervals. Classifying the segment of scanned radio frequency data into a radio frequency environment includes comparing a set of statistics extracted from the segment of scanned radio frequency data to pre-defined classification ranges.

Abstract: A terminal obtains a monitored set containing GSM neighbor cells and/or UMTS neighbor cells. The terminal operates in a compressed mode and obtains from a UMTS network at least two transmission gap pattern sequences for different measurement purposes, e.g., for “GSM carrier RSSI measurements” (GAP1), “GSM initial BSIC identification” (GAP2), and “GSM BSIC re-confirmation” (GAP3). The terminal makes RSSI measurements for the GSM cells using multiple transmission gap pattern sequences, e.g., using GAP1, GAP2 and GAP3. The terminal identifies the BSIC for at least one GSM cell by (1) detecting the tone on the FCCH using multiple transmission gap pattern sequences, e.g., using GAP2 and GAP3, and (2) decoding the SCH using multiple transmission gap pattern sequences, e.g., using GAP2 and GAP3. The use of multiple transmission gap pattern sequences for RSSI measurement and BSIC identification allows the terminal to complete the cell measurements and send a report sooner, which may improve performance.
